Looking for a new look on your existing deck, Duck Boards are a great option and user friendly?August 22nd 2016
Q. I am planning to cover a coated deck over a carport with cedar decking. I can't nail the new decking material down or the nails will pass through the deck to the carport. Is there another way that I can secure the decking material?
A: Instead of attaching a full wood deck, install wooden duck boards over top of the deck surface. You can make your own or you can purchase them at building supply stores including Windsor Plywood Stores.
To make your own duck boards you will need 24-inch, 1" x 2" cedar strips and galvanized 1-1/4" box nails. Make the 24" x 24" squares by nailing the strips to four pieces of 1" x 2" running in the opposite direction (those will be the "runners" for the bottom side.) Leave a nail thickness between the boards. Set the squares on your deck in opposite directions to give your deck a parquet design. Water will run freely between the 1" x 2" bottom runners to the drains and away, leaving a dry surface to walk on.
There are a number of recycled plastic grids available on the market today for the same purpose. Check your local building supply store for availability.
